Massachusetts preempts local bans on personal cannabis cultivation under MGL c.94G §7, allowing adults 21+ to grow up to six plants per person and twelve per household statewide.
Under MGL c.94G §7, an adult 21 or older may cultivate up to six marijuana plants for personal use, with a maximum of 12 plants per household regardless of the number of adults. Plants must be grown in a locked area not visible from public space. Municipalities cannot prohibit personal cultivation, though landlords may restrict it in lease agreements. The Cannabis Control Commission oversees licensed operations under MGL c.94G but does not regulate personal home grows.
Exceeding plant limits, growing in public view, or cultivating without securing the area can result in civil penalties up to $300 for first offense and possible criminal charges for larger amounts.
